‘The great mystery of Ephesians 6 is that God bestows his own armor on his people. The medium of the great gift is first Jesus Christ, God’s Champion, who is depicted by the OT and the NT as clothed in the same armor as YHWH, wielding his ferocious long sword against his people’s enemies (Is 11:4–5; 59:16–17; Rev 1:13–16; 19:11–15). But Ephesians takes this one step farther by arguing that, since the Christian is mystically “in Christ,” this armor is bestowed on everyone baptized into him.’
